Hey I started a Ranger on GWNF and I was wondering how can I catch a pet and where can I get armor and a good weapons for the future?

If I add henchmen to the party, will the experience be shared? and if only me and my hero are in the party will the experience be shared?

You can catch a pet by equipping the skill "Charm Animal" and clicking it once a hostile animal is approaching you.

Experience will be divided between the characters in the party. So say you defeat a 100XP enemy beasty, experience will be awarded like this:

1 Character - 100 XP each
2 Characters - 50 XP each
3 Characters - 33,3 XP each (I'm not sure if it's rounded up or down)
4 Characters - 25 XP each
5 Characters - 20 XP each
6 Characters - 16,6 XP each
7 Characters - 14,3 XP each
8 Characters - 12,5 XP each

Pets have to be green (Netural) when you start to tame them, then they will go hostile.

It's important to stop any NPCs from attacking the pet as you cast the skill, if they kill it you lose it.
